"To one whose mind is free, there is something even more intolerable in the suffering of animals than in the sufferings of humans. For with the latter, it is at least admitted that suffering is evil and that the person who causes it is a criminal. But thousands of animals are uselessly butchered every day without a shadow of remorse. If any person were to refer to it, they would be thought ridiculous. And that is the unpardonable crime. That alone is the justification of all that humans may suffer. It cries vengeance upon all the human race. If God exists and tolerates it, it cries vengeance upon God." Jean Christophe.
